Abstract
An automatic control emergency shutoff valve comprises a stop valve, a valve body, two shift levers, a valve rod, an overflow controller, a floating flap, a compression spring and a hydraulic cylinder, wherein the stop valve is provided at the upper of the valve body, the hydraulic cylinder is provided at the outer side of the valve body in which the overflow controller, the floating flap and the compression spring are provided, the inner and outer sides of the valve body are respectively provided with a shift lever, the inner shift lever is connected with the valve rod, and the outer shift lever is connected with the hydraulic cylinder. The automatic control emergency shutoff valve has the advantages that via the overflow automatic control function, the utility model can safely transmit medium.
Description
Technical field
The utility model relates to a kind of autocontrol valve, but what be specifically related to is a kind of automatic control type Emergeny Cutoff Valves.
Background technique
Emergeny Cutoff Valves is the main gateway gas, liquid charge and discharge valve of liquid gas haulage device, bunkerage.So-called emergency cut-off, be exactly when liquid gas in cargo handling process, contingencies such as fire, pipeline fracture, overturning, stop valve be malfunctioning appear, this valve can pass through the rapid emergency cut-off of pressurized oil system automatic or manual.It is one of safety attachment indispensable on the pressurized container storage and transportation equipment.But the liquid phase Emergeny Cutoff Valves in past does not install overflow protecting element additional.So-called overcurrent protection is exactly in the medium cargo handling process, and when media flow speed surpassed permitted value, this element can be closed automatically, makes the media flow speed controlling below permitted value.Uncontrollable its flow velocity in loading and unloading material process, it does not meet the regulation of GB50074-2002 " oil depot design code ", this standard code: the loading-unloading vehicle flow velocity should be greater than 4.5m/s, be in order to prevent electrostatic hazard, be convenient to the control of loading-unloading vehicle amount, reduce oil gas volatilization, reduce the water attack of pipeline.
Summary of the invention
But providing, the purpose of this utility model has a kind of automatic control type Emergeny Cutoff Valves that overcurrent is controlled function automatically, can be satisfied the requirement of safe transport medium.
The technological scheme that adopts is:
But a kind of automatic control type Emergeny Cutoff Valves, comprise stop valve, valve body, driving lever, valve rod, cross flow-control element, unsteady flap, pressure spring, hydraulic jack, stop valve is positioned at valve body top, the valve body outside is equipped with hydraulic jack, flow-control element, unsteady flap, pressure spring were installed in the valve body, the outside respectively is equipped with a driving lever respectively in the valve body, and inboard driving lever is connected with valve rod 4, and outside driving lever is connected with hydraulic jack.
Above-mentioned flow-control element, the flap that floats are to be enclosed within on the valve rod, and in installation and the valve body.
Stop valve partly links to each other with cut-off valve by valve body; pressure spring guarantees the normal sealing of cut-off valve under the normal transport state, and hydraulic jack promotes valve rod by driving lever and opens the cut-off valve part downwards, in the medium cargo handling process; when media flow speed surpasses permitted value, the overcurrent protection dress
Put and to close automatically, cut off the circulation of medium, make the media flow speed controlling below permitted value.
Advantage of the present utility model is: have overcurrent and control function automatically, can satisfy the requirement of safe transport medium.
